About SMP

Most of the features of this mod are client side and don’t need any support from the server, with a few exceptions:

If you have this mod installed on the server, special crafting tables (Forestry Worktable, ME Pattern Encoder, etc.) can set the recipe with shift+click even if you don’t have the items on you. It will also be more reliable and less prone to lag-related glitches.

AE2 Cell Workbench drag&drop support requires NEI Addons to be installed on the server.

Seeing all bees, saplings, serums, pollen in NEI search requires NEI and CCC installed on the server. This is an NEI limitation that affects all items with NBT data.
